| contents | Controlling heat flow at the quantum level is a key challenge for next-generation quantum technologies, including thermal management and quantum information processing. Here, we investigate quantum heat transport in an asymmetrically driven hybrid magnon-photon system in contact with two thermal baths at different temperatures. We demonstrate that external driving of the magnonic subsystem provides a versatile control knob for tailoring steady-state heat currents and their asymmetry. We identify the mechanisms governing thermal rectification in the hybrid system: we find that strong rectification emerges in the regime of weak magnon-photon hybridization combined with intense magnon driving. In this regime, the external drive enables control over both the magnitude and direction of the heat current, allowing the rectification parameter to be tuned across its entire physically accessible range. |
